T 0 all whom it may concern:

Be it known that 1, DAVID WV. MoCLAY, a citizen of the United States, residing at Schenectady, in the county of Schenectady and State of New New York, have invented a new and useful Improvement in an Axle- Cutter, of which the following is a specification.

This invention relates to an axle cutter designed for recutting worn axles, and theobject of the invention is an axle cutter in which the cutting tools are adjustable so that the device can be used, upon axles of various types and sizes.

The invention consists in the novel features of construction, hereinafter fully de scribed, pointed out in the claims. and shown in the accompanying drawings, in which,

Figure 1 is a side elevation of my cutter. Fig. 2 is a vertical section taken longitudinally through the cutter. Fig. 3 is a front elevation. Fig. 4 is an end view the axle being in section. Fig. 5 is a detail perspective view of a bracket for holding one of the cutting tools.

This device consists essentially of three parts, a cylinder A, a ring B and a disk C, which carries the cutting tools.

The cylinder A supports the disk O and also carries locking means for holding the axle rigid, and the ring B serves to couple the parts together. The cylinder A is formed with an exterior annular shoulder which engages the shoulder A and limits movement of the ring B in one direction. The main portion of the ring B is interiorly threaded and the disk C is centrally cut out as shown at C, and is provided at its inner face, with a hub portion 0 encircling the cut out portion C and exteriorly threaded. This hub portion is adapted to be threaded into the ring B. On its front face the disk C is provided with a casting D cored out as shown at D and through the slot thus formed works a cutter D held in its adjusted position by a set screw D On the front of the disk C and on the side of the opening C opposite to the casting D, is an outwardly extending bracket E, longitudinally slotted as shown at E, and a block F slides in the said slot.

The block is provided with a reduced threaded portion F, and awasher F fits over this threaded portion and bears against the bracket E, and is held in place by a nut F The block F is slotted and the cutter H is adjustably held therein, one side of the cutter being brought into contact with the bracket E when the nut F is tightened. Through the cylinder A work a plurality of threaded rods H, which serve to center and hold an axle K. The disk C has a radial groove C formed on its outer face, and a handle J, rests in the said groove, and is secured to the disk by suitable screws, so that it is readily detachable.

In operation the axle is centered by the threaded rods H, and the cutter D is adjusted in the casting D and brought into engagement with the axle shoulder and the block F is adjusted along the slot E to the proper position, and the cutter G is properly adjusted in the block and the nut F then tightened, locking both the block and cutter in their adjusted positions.

When the cutters D and G are set as shown inFig. 1, they are in position to commence the cutting operation, both cutters being a fixture upon the disk C which can be rotated in either direction by means of the handle J. The tools D and G are reversible with respect to their cutting edges, and in practice the disk C is rotated right handed, the cutters D and G being set to cut with the disk C rotating in that direction. As the disk C revolves on the shell or cylinder A it carries both tools about the axle, the cutter D cutting the shoulder of the axle and the cutter G cutting the end of the axle, and both must cut the same amount of stock. It will be obvious that if the cutter G cut more of the stock lengthwise than the cutter D the nut to be used on the axle would not fit on far enough. When the ring B is in place it becomes a part of the disk C and turns with it. The brass ring B is knurled and when the hand is rested on the ring B and its rotation is stopped, and rotation of the disk is continued, the threads on the hub C of the disk C will cause the hub to travel in the ring, drawing the ring and disk toward each other and feed the cutters to their work, the ring B acting as a nut on a bolt. By using both cutters at once and arranging them opposite to each other the device is balanced.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. An axle cutter comprising a cylinder, a disk having a hub adapted to slide and rotate on said cylinder, said hub being exteriorly orly threaded hub portion fitting Within the ring, and cooperating cutters supported from 10 the disk. 7
